Similar reference eharaaters designate similar parts in the differentVTGWSr I pi ovide a suitable supporting;- frame comprising; preferaihhna table having; a. box to 1 provided withlegs 2;- Two longi t-ud inalhave their" lower edges resting; u'pow vertiralt screws 4:1fii-b8d' inscrew threaded holes in the'bott'omof -the tarble top 1. The guideplates 3 are clamped, in sneh! positions as they may be venti-eallyadjusted by the screws 4, to the inner sides respectively of the boxtop-1 by clamping-plates5;: which are-secured to thebox top 1" by bolts 6;

Upon'the bottom-of the box top 1 between the guide plates-3 and spacedapartthere fre'ini's a mold frame 7 of-reetan'gular form to the innersides 0% which are respectively secured bybolts S'eXtendin-gthroughslots 9, vertically adjustable side mold members 10 guide plates 3disposed edge up and end mold members 11, the bolts 8 being litted inscrew threaded holes in the sides of the mold frame 7.

Between the mold members 10 and 11 is adapted to be mounted a die plate12, the upper side of which forms the under side of the cement tile 18,the upper side of which is formed by a forming tool 1% having bearingsurfaces 15 on its under side respectively adjacent to its ends, Figs. 2and 9.

The under side of the central portion of the forming tool H is of thecontour of and forms the upper side of the tile 13. The upper edges ofthe end mold members 11 are fitted to this central portion of theforming tool, so as to permit the tool to pass across them. The formingtool 11 between the central portion and the guide plates 3 is providedwith hand holds 16 by means of which the operator manipulates the tool.Inter mediate of the hand holds 16 and the bearing surfaces 15, the tool11 is provided with downwardly extending projections 17 whichrespectively engage the inner sides of the guide plates 3 to limit theendwise momment of the tool, or to prevent any endwise movement, as maybe desired.

The upper edges of the guide plates 3, and the bearing surfaces of theforming tool 14 are horizontal, while the under side 19 of the centralportion 18 of the forming tool, is inclined upwardly and to the left, asshown in Fig. 3. The left or forward longitudinal side of the formingtool 14, as viewed in Fig. 3, is sharp and inclines upwardly andrcm'wardly, so that upon the tool being slid forwardly, that is to theleft, as viewed in Fig. 3, the sharpened forward edge will cut away andforce forwardly the excess cement and sand. As the under side 19 of theforming tool inclines downwardly and rearwardly, the tile material willbe packed and smoothed thereby, and will not be rough, as would be thecase if the bottom of the tool at its central portion were horizontaland parallel with the plane of movement of the tool.

For supporting the die plate 12 in the operative position, shown inFigs. 2, 3 and 5, there are provided between the mold members 10 and 11and adjacent respectively to the corners of the mold frame 7, fourvertical screws 20 which are respectively fitted in threaded holes inthe bottom of the box top 1 of the table. Lock nuts 21 are respeclivelymounted on the screws 20 and are adapted to bear against the box top 1.

For lifting the die plate 12 above the mold members 10 and 11, as shownin Fig.4, so that the plate with the molded tile thereon may be readilyremoved from the machine, there are provided two vertically slidableupright rods 22 which extend through and are slidable in holes providedin the table top 1, and which have inwardly turned upper ends adapted toengage and lift the adacent end 0" the die plate 12. The lower ends ofthe rods 22 are respectively pivoted to the anus of a U shaped lever 23,the arms of which are respectively pivoted by hori- Zontal bolts 2 1 tothe arms of an inverted U shaped bracket 25, the transverse portion ofwhich is secured to the under side of the table top 1.

The other end of the die plate 12 is adapted to be lifted by thetransverse portion of an inverted U shaped member 26, the vertical armsof which extend through and are vertically slidable in holes in thetable top 1. The lower ends of the arms of the member 26 arerespectively pivoted to the arms of a U shaped lever 27, the arms ofsaid lever being respectively pivoted by horizontal bolts 28 to the armsof an inverted U shaped lHItICkGt- 29, the transverse portion of whichis secured to the under side of the table top 1.

To swing the members or levers 27 and 23 so as to litt the member 26 androds 22 and the die plate 12, there is provided a horizontal shaft 30having a crank 31 and rotatably mounted in bearings 32 depending fromand secured to the table top 1. The shaft 30 is provided with two camarms 33 which are adapted, when the shaft is turned counter clockwise,as viewed in Figs. 3 and 4, to strike the under sides of the arms of thelevers 23 and 27, thereby, on continued turning of the shaft 30 to theposition shown in Fig. 4, lifting the die plate and formed tile 13 tothe elevated position above the mold members 10 and 11.

For forming on the upper side of the tile 13 adjacent to one end thereofan arcuate transverse flange 34, there is provided a longitudinallslidable mold member 35, which has its en s slidably mountedrespectively in two longitudinal grooves 36, which are respectivelyprovided in the inner sides of two upright plates 37, which arerespectively secured to opposite longitudinal sides of the mold frame 7.The mold member 35 is adapted to be moved from its outer position. shownin Fig. 4, over the adjacent end mold member 11 to the inner sidethereof, as shown in Fig. 3. When the mold member is in the positionshown in Fig. 3, its lower edge is above and spaced apart from the dieplate 12. It is also above the lower side of the forn'iing tool 14. Thelatter is provided at its rear longitudinal side with a vertical portion38 which extends above and below the lower edge of the mold member Whenthe mold member 35 is in the opera tive position shown in Fig. 3, andthe tile material has been deposited upon the die plate 12, and betweenthe mold members 10 and 11, the operator, by properly sliding theforming tool 14 to the right, as viewed in awns.

Fig. 3, on the guides 3, will tome the tile material against theadjaocidend plate 11 and under the lower'cdge oh the movable mold member35, therein forming the arouate transverse flange 34' on the upper sideprovided a horizontal transverse rock shaft 39, having its ends pivotedrespectively-in opposite sides of the mold frame 7. The rock shaft 39 isprovided with two radial arms it), the upper ends of which areprovidedeach with an eye through which ex tends a removable horizontal bolt 41',which also extends through and is vertically slidable in vertical slots42 provided respite tivcly in two rcarwardly extending cars 43 whichextend outwardly from the mold member 35. hen the rock shaft 39 isoscillated, the arms 40tl1ereof will reciprocate the mold member 35. Forswinging the rock shaft 39, it has extending radihlly-anddownwardiy fromice crank arm 44, which ex tends through a slot 45 in the table top 1,and which has pivoted to its link-46; which is pivoted at its other andto e crank 47, with which the crank sha*ft*3 0 is provided. Thearrangement is such that when the crank shaft 30 is swung from theposition shown in Fig. 3 to that shown in Fig. 4, the mold member willfirst be moved so as to clear the inner side oi": the adjacent moldmember 11, after which the cam arms 33 will swing the levers 27 and soas to lift the die plate 12 to the elevated position shown in Fig. 4.

For forming a hole end of the t iflel3, as shown in Fig. 3, tit-ere isprovided needle 18, which is radially adjustable in a 'hole through therock shaft 39,to whic rthe" needle" isseeured-bya set screw 49."*he-otherend of the see-die 48'is curved and is adapted-to pass throughtwo holes 50 aridfiil id'themolii frame? and adjacent end moldmc'niber11, as shown in Fig. 3. In the operative position, the needle willstrike the upper side of'the die plate 12. The portion of the needlewhich enters the meldhas the form- 01 a. curve,the center of which istheaxisflof the rock shaft 39.

For farming a mien-the bottom'of the tile 13, adjacent to the middleportion thereof, there is provided a curved needle 52, Fig. 5", which isclamped between two angular levers 53, secured together by a screw andpivotally mounted on a h0ri-- zontal bolt 55, which extends through andis fastened to two arm'sof'a lever 56,0116- end for a nail is the rightof whioh rests upon the table top: 1, and the other end ofwhioh restsupoir a vertical screw 57, fitted in a screw-threaded-hole in thetabletop 1', whereby the-axis of the an gu'lar levers 53 may bevertically adjusted. A vei ti'calscrew 58 extends between the arms'ofthe lever .56 and clamps the lever to the table top.

The needle 52 is adapted to enter a hole 5!) prm'idecl in the die plate12, which holc communicates with a depression 60 provided in theupperside of the die plate 12 for the reception of tile material. The end ofthe needle 52 is adapted to strike the wall of the depressed portion, asshown in Fig. 5. VVhelr the needle is in the position shown in Fig. 5,and the tile material is placed upon the die plate 12, it will fill thedepres sion 60, around the needle 52. When the needle is withdrawn, itwill leave a hole which extends through the lug on the under side of thetile formed by the depression (31'). A link 61 has its ends pivotedrespectively to the levers 53 and the crank arm ll.

The upper side of the die plate 12 is proridcdadjacent to one cornerwith an oblique rib 62, Fig.1), which forms a groove in the under sideof the tile 13, whereby the tile at this place is weakened so that thecorner may be easilw broken oil, as is shown in Figs. 6 and 8.

The upper side of the die plate 12 adj arent to the corner diagonallyrelated to the rib 62 is provided with a rib having an oblique portion63, which at its inner end connects with a longitudinal portion (34,whereby the tile is weakened so that the adjalent corner may be readilybroken away.

The under side of the tile 13 has formed in it a recess 65, F ig. 7,which is formed by a transverse raised portion 66, on the upper side ofthe die plate 12. The groove 65 is much wider than the width ofthearcuate flange 34, which is formed onthe' upper side of the tile 13adjacent to the end distant from that provided with the recess 65.

When the tiles are fitted together as shown in Fig. 6, the flange 34. ofthe lower tile fills in the groove 65 of the tile next above. By havingdiagonal corners obliquely brokenaway, as shown, the overlap of thetiles may be varied a considerable amount to correspend with thedistance between the strips to which th'e tiles are secured.

At the same time, the joints will be covered so that leakage willbeavoided.

In the operation of my invention, the initial position of the parts,with the exception of the forming tool"14,will be as shown in Fig; 3.Shfllienttil making' material is then placed upon the die plate 12,after which the forming} tool 14 is employed to pack the material underthe movable mold member 35 so as to form the flange 34 011* theupperside of the and. After this has been done, the forming tool 14 ismoved away from the mold member 35, and being slid along on the guideplates 3, the sharpened forward edge of the forming tool 14, removes theexcess material and pushes it forwardly, while the inclined under Sideof the forming tool 14: smooths and properly forms the upper surface ofthe tile.

The crank shaft 30 is then turned counterclockwise by the crank handle31, as viewed in Figs. 3 and 4, thereby swinging the needles 48 and 52out of the formed tile, by means of the mechanism already described. Atthe same time, the mold member 35 will be moved to the outer side of theadjacent mold member 11. Continued turning in the same direction of therock shaft 30 will cause engagement of the cam arms 33 with the levers27 and 23, thereby swinging said levers so as to lift the die plate 12to the position shown in Fig. 4, by means of the rods 22 and the member26.

Upon retracting the crank shaft 30 to its initial position shown in Fig.3, the levers 23 and 27 will swing downwardly by gravity, thus forcingdownwardly the rods 22 and the member 26, to the position shown in Fig.3. The new die plate 12 carried by said rods 22 and member 26 will becarried between the mold members 10 and 11 and will rest upon the screws20. At the time the die plate 12 is brought to bear upon the screws 20,the mold member 35 and the needles i8 and 52 will move into theiroperative positions shown in Figs. 3 and By having the mold members 10and 11 and the guide plates 3 and screws 20 vertically adjustable,compensation for wear due to the sliding back and forth of the formingtool 14 will be afiorded.

By spacing the guide plates 3 at a considerable distance apart from themold frame 7, the guide plates will be clear of cement and sand, therebygreatly reducing the wear upon them,
